How is SUV calculated using Body Surface Area (BSA)?

The correct calculation for Standardized Uptake Value (SUV) using Body Surface Area (BSA) is based on the formula that relates the injected tracer dose to the tracer concentration in a Region of Interest (ROI). The SUV is designed to normalize the uptake of the radiotracer in a specific tissue with respect to the body size of the patient, which helps to make comparisons between patients with different weights and sizes more accurate.

In the correct formula, SUV is calculated by taking the tracer concentration in the ROI (measured in mCi/cc) and dividing it by the dose of the tracer administered, adjusted for body surface area (mCi/m^2). This approach allows for a standardized understanding of how much of the radiotracer is taken up by a specific area of tissue relative to the overall body size. By using BSA, the SUV calculation accounts for individual variations in body composition, ensuring a more reliable assessment of the radiotracer uptake in the context of the patient's metabolism and physiology.

The other options present variations that do not correctly represent the relationship between tracer concentration and total body dose in relation to BSA, either by employing incorrect mathematical operations or incorporating elements that do not belong in the SUV calculation.
